So I got my recently acquired 91 rt tt running pretty good by having the ecu refurbished. I have only driven it a few miles since but I am really starting to want to keep it. The car has 150,000 miles but is very clean and seems like it has been looked after. The engine is original and the heads have never been off. Am I getting myself into a nightmare by keeping one around with mileage like this? Is it common for these cars to blow engines, headgaskets, turbos etc? It Seems to have good oil pressure, doesn’t overheat. Anything else major I should look for? Check engine light is on so I will look into that. Thanks!

If you keep up on scheduled maintenance and look out for things like dented oil pans you should be fine. Doing your own work or having someone familiar with the platform do the work is key. It seems like the bulk of mechanics these days specialize in brake jobs and anything more complex will result in destruction of your car lol.

Check for dents in your oil pan, change your oil every 3000 miles, let it get up to temperature before you do any spirited driving, and keep up with the recommended maintenance schedule. Do all that and it will give you 200,000+ miles easily. So long as you don't red line the crap out of it every time you drive it or whatnot.

I totally agree with this. The car is rare in my country. No mechanics ever do the job with this type of car to be a specialist. So, I need to find out the problem by doing some research before going to mechanics to do works that I cannot do. Do not rely on any mechanics at all. They can do things but they don't know as much.

+1, good summary.

Also more generally speaking, just check on things much more than you would a modern/new car, especially before hard driving... check fluids, belts, hoses, connections, etc. You want to catch things before they happen.

Thank you, I plan to go over the whole car and change all the fluids, look for anything obvious that is worn etc.
